The correct answer is:
B. purebred is a term used for a homozygous organism, and hybrid is a term used for a heterozygous organism.
**Explanation:**
- A **purebred** organism has two identical alleles for a trait (homozygous), either dominant or recessive.
- A **hybrid** organism has two different alleles for a trait (heterozygous), consisting of one dominant and one recessive allele.
